Patented Aug. 10, 1937 UNITE STATES PATENT .OFFICE 1 Claim.

The present invention relates to combined wood and brick walls of the type commonly known as brick veneer. In making such walls a wood frame is first made, comprising vertical studs to which external boarding is attached. A layer of paper is then secured to the boards, usually by the use of laths. Courses of brick are laid a short distance from the frame and are supposed to be tied to the Wood at fairly close intervals. The usual tie simply comprises a sheet of metal which is nailed to the frame and extends out over a previously laid course of brick. Such a tie is inconvenient because it is necessary for the mason to lay aside his other tools and pick up the hammer to drive the nail; furthermore, the nail is somewhat inaccessible because its position is just above and in back of the brick which has just been laid. In view of this inconvenience, it is frequently a practice of the workmen to leave out some of the ties with the result that the brick wall is not suitably connected to the frame. An additional difficultyv arises from the fact that the position of the studs is not apparent after the paper is laid so that the brick wall may be tied at a number of points to the thin boarding rather than to the studs.

The object of the present invention is to provide a veneer wall construction in which the tying of the brick may be so conveniently accomplished that there is no incentive to omit the necessary number of ties, and a further object is to afford a construction in which maximum strength due to regular spacing and application to the studding is assured. Y

With these objects in view the present invention comprises the wall hereinafter described and particularly defined in the claim.

In the accompanying drawing Fig. 1 is a hori- Fig. 2 is a detail sectional view on an enlarged scale of the preferred brick tie.

In Fig. 1 there is illustrated a composite wall comprising vertical studs 2, to which an inner finish wall Il of any suitable form may be applied. Externally of the studs there is a planking 6 of matched boards to which a layer of paper 8 is applied. The paper is unrolled and laid in horizontal strips and is secured to the frame by means of the brick ties themselves which therefore serve a double function. To this end the tie members include a series of channels designated at I0 in Fig. 2. Each channel is of the shape specifically shown in Fig. 2 with a fiat back portion I2 and curved edges which terminate in front portions I4 parallel to the back wall I2. A central slot appears between the edges of the portions I4. The channels are preferably of a length approxi- (Cl. 'Y2-103) mately equal to the width of the paper, and may be attached to all of the studs extending throughout the height of the frame, although alternate channels in each row may be omitted, if desired. Each channel is provided with a series of holes in its rear face and the channel is attached to the studs by nails I6. As indicated in Fig. 1 the nails are preferably of the double head type to permit application of the hammer blows without damaging the channel. f

The work thus far described is done by the carpenter. The mason then lays courses of brick in the usual manner, these being spaced a short distance away from the wood frame. At regular intervals the brick is tied to the frame by means of key members indicated at I8. Each key member is a stamping of sheet metal with a portion 2l] conforming closely to the cross section of the channel and a protruding tongue 22 adapted to overlie the course of brick. Preferably the tongue is provided with a stamped hole 24 to provide for an additional bond with the mortar. In applying the key member it is merely inserted sidewise into the channel and turned into horizontal position, and then simply brought to the level where it rests upon the brick. The next course of brick is laid in the usual manner over the ties so that after the mortar sets the brick wall is firmly secured to the frame. It will be noted that the shape of the channel with parallel front and rear walls is such as to provide maximum resistance to distortion against the tendency of the brick wall to pull away.

The advantage of the present brick tie is rst that it provides a means of holding the paper without any greater effort in its application than the usual lath, and second that it assures a complete and rigid connection between the brick and wood. Since the channels are put up when the paper is laid there is no occasion to nail them anywhere except at the studding. Furthermore, the application of the key members by the mason is simple and is accomplished without the use of any tools so that there is no incentive for omitting any of the necessary ties.

Having thus described the invention, I claim:

A composite wood and brick wall comprising studding, external planking, a layer of paper, means for securing the paper to the outer surface of the planking including a vertical channel member nailed to the studding, a brick wall external to the planking and spaced therefrom substantially the thickness of the channel member, and tie members having portions secured within the channels and tongues extending therefrom and lying between adjacent courses of brick.
